Nice kit, with clear results!

The instructions are clear and I could easily tell on the chart what my results were.

Good, Easy to Use

This kit came with clear instructions, making it easy to use and easy to interpret the results.
The only guidance it didn't come with was what to do with the chemicals/soil after the test - it would be helpful to have some instructions on proper disposal and clean-up.

La Motte Soil Test Kits

I am a middle school science teacher and I use these kits with my students in a soil project. They learn to test soil for nutrients and pH while studying the Periodic Table and the interactions between plants and the soil ecosystem. There are great reference materials for better understanding of soil and easy to follow directions. I wouldn't consider having my students use any other kits. And I received them very quickly after ordering. Thank you!!

A soil test kit with easy to follow instructions at a reasonable price

Test provides necessary data regarding soil to avoid under or over fertilizing. It is easy to use with step by step instructions. It appears that greatest place for error is cleaning the test tubes without rinsing using distilled water. Price is reasonable. This test kit is. It for someone who fails to follow instructions as it is not intuitively obvious regarding each test process.
